If you find yourself driving down River Highway in Mooresville, NC this summer and suddenly smell a vaguely steak-like odor, don’t worry, you’re not having a stroke. You’re passing by the billboard for Bloom, a supermarket chain that’s owned by Food Lion. The billboard went up last Friday and poots out a charcoal-and-pepper fragrance from 7 to 10 a.m. and again from 4 to 7 p.m.
